It's not telling you where your ISP is headquartered. It's telling you where the servers that you're connecting to are. In your case, you're connecting to servers that your Athens-based ISP has in a Thessaloniki datacenter. The only way to get an accurate location is to use something other than IP- phones like to use a combination of their GPS, a map of the cell phone towers, and a map of wi-fi hotspots (this is one of the things that Google's StreetView cars log as they drive). -- http://mail.python.org/mailman/listinfo/python-list
